Discussion | Of conservation concern. Delphinium purpusii is not likely to be confused with any other Delphinium in North America. Hybrids with Delphinium hansenii subsp. kernense are known to occur. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Delphinium geraniifolium is a more pubescent analog of the closely related D. scopulorum, the former occurring in heavier soils at higher elvation. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
